The timeout goes away if max_sectors is decreased to ATA_MAX_SECTORS - 1, doh. But both the reading and writing are seriously broken. I can't tell whether they end up in the wrong sectors or garbage is transferred to/from the right sectors. I'm really close to marking this device broken or we'll need to implement a mechanism to veto LBA48 device from LLD (may be negative return from ->dev_config). Reading the sunix driver, I can't find any relevant workaround. It never seems to initialize ctl address. I'm curious whether the sunix driver can do LBA48. Bob, are you interested in testing this?
